INDEX CLIP Filed July 14, 1937 flifo rnez/ Patented May. 24, 1938 UNITEDSTATES "earns OFFICE Claims.

(Granted under the act of March 3,1883, as amended April 30, 1928; 3700. G. 757) This invention described herein may be manufactured and usedby or for the Government for governmental purposes, without the paymentto me of any royalty thereon.

This invention relates generally to marking devices, but moreparticularly to an index clip which may be attached to the leaves ofbooks, filing cards, etc.

One object of the invention is to provide a detachable clip which willbe particularly adapted for use in filing or bookkeeping.

Another object of the invention is to provide an index clip of simpleand inexpensive construction which may easily be attached and releasedfrom the leaves of books or cards without injuring the edges thereof.

With these and other objects in view, this invention consists in certainnovel details of construction, combination and arrangement of parts tobe more particularly hereinafter described and claimed.

Referring to the accompanying drawing in which corresponding parts areindicated by similar reference characters:

Fig. 1 is a perspective view of the index clip;

and

Fig. 2 is a perspective view showing the clip attached to the leaf of abook.

Briefly stated, the invention comprises an index clip consisting of atag and a resilient engaging means connected thereto adapted foryieldable attachment to a sheet of paper, a card, leaves of a book orcloth, etc.

The resilient engaging means or clip indicated in the figures by thenumeral I, consists of a single piece of resilient wire bent to form asupporting loop 2, and two partially overlapping engaging loops 3 and 4,all of which lie in a single plane when the clip is not attached to thearticle to be marked or indexed.

The loop 2 is preferably made in rectangular form and a tag 5 is formedwith a central slit or opening 6 through which the terminals 1 and 8 ofthe loop 2 are threaded before the loops 3 and 4 are formed.

The terminals or extending ends 1 and 8 of the supporting loop 2 arethreaded through the opening 6 in the tag 5, and the tag is folded on aline through the opening 6 along the side of the supporting loopadjacent the extending ends 1 and B, and the inner surfaces of the sides9 and ill adhesiv-ely united to inclose between them the supporting loop2. The extending ends of the supporting loop are bent to form partiallyoverlapping engaging loops 3 and 4 adapted to straddle the edge of sheetmaterial and yieldably engage the same. A clamp II in the form of a flatlink is clamped around the portion of the terminals 7 and S-adjacenttheloop 2, to firmly hold the overlapping loops 3 and 4 in theirrelative positions. If desirable in the manufacture of the device therelative widths of the opening 6 in the tag and of the engaging loops 3and 4 may be made such that it is possible to thread the loops throughthe opening 6, and thus entirely complete the formation of the engagingand supporting portion of the device and the tag before assembling. Thetag is folded over the straight portion of the edge of the supportingloop adjacent the extending ends 1 and 8 to allow an even pressure alongthe line of fold and thus avoid tearing.

To attach the index clip to a sheet of paper or a card the outer loop 4is brought into contact with the edge thereof and the clip is thenpressed slightly to spread apart the loops 3 and 4. The clip is thenpressed onto the sheet so that the loops 3 and 4 straddle the edgethereof, and are retained thereon due to the resilience of the materialof which the clip is formed.

Having described my invention, what I claim as new and wish to secure byLetters Patent is:

1. In an index clip, the combination of an engaging member and a tagprovided with a central opening, the engaging member comprising a singlepiece of resilient material, bent toform a rectangular loop withprojecting ends threaded through the central opening in said tag, thetag folded on a line through its central opening and its sidesadhesively united to enclose said supporting loop, and the projectingends of the latter bent to formpartially overlapping engaging loopsadapted to straddle the edge of sheet material to yielclably engage thesame.

2. In an index clip, the combination of an engaging member and a tagprovided with a central opening, the engaging member comprising a singlepiece of resilient material, bent to form a rectangular loop withprojecting ends threaded through the central opening in said tag, thetag folded on a line through its central opening and its sidesadhesively united to enclose said supporting loop, the projecting endsof the latter bent to form partially overlapping engaging loops adaptedto straddle the edge of sheet material to yieldably engage the same, anda clamp attached to projecting ends of said supporting loop adapted toretain the partially overlapping loops in their fixed relative position.

3. In an index clip, the combination of an engaging member comprising asingle piece of resilient wire formed as a rectangular supporting loopwith the ends of said Wire extending centrally from one of its straightrectangularly disposed sides, and a tag provided with a central openingthrough which the extended ends of the supporting loop project, said tagbeing folded centrally through the opening along the straight side ofthe rectangular loop adjacent said extending ends to avoid tearing bycontacting an even pressure surface along the line of fold, the innerfaces of the extending sides of said tag adhesively connected to inclosesaid loop, and the extending ends of said supporting loop bent inoverlapping relation to form engaging loops providing a yieldable clamp.

' 4. In an index clip, the combination of an engaging member comprisinga singlepiece of resilient wire formed as a supporting loop providedwith a straight portion from which the ends of said wire extend, and atag provided with a central opening through which the extended ends ofthe supporting loop project, said tag being folded centrally through theopening and along the straight side of the rectangular loopradjacentsaid extended ends to avoid tearing by contacting an even pressuresurface along the line of fold, and the inner faces of its extendingsides adhesively connected to inclose said loop, and the extending endsof said engaging member bent to form overlapping engaging loopsproviding a yieldable clamp.

5. In an index clip the combination of an engaging member comprising apiece of resilient wire formed as a supporting loop provided with astraight portion from which the ends of said wire extend, the extendingends of said supporting loop being bent in overlapping relation to formengaging loops providing a yieldable clamp, a tag provided with acentral opening through which the engaging loops are passed, said tagbeing folded centrally through the opening therein along the straightportion of the supporting loop to avoid tearing by contacting an evenpressure surface along the line of fold, and the inner faces of theextending sides of said tag adhesively connected to inclose said loop.
